Andrew - I see you are in the UK. I got my 7-14 for just over £500 here used, there was an internet seller with good reviews selling them new for mid £600's in Scotland not too long ago. I often consider 9-18 as well believing it may save me lens changes between 7-14 and 14-45 - but it seems to me to be hard to get the Oly 9-18 in micro 4/3 much under £400 even used, making the price differnce much less than appears - so I have not so far justified it, as also have Rokinon 7.5 plus a long one for the odd wildlife.

When I jumped from FF - Sony and Nik D700 before that to OMD on launch the 2 lenses I bought before camera even arrived were 7-14 and 14-45 Panny's. This was because as a simple hobbyist I love the ultra wides, always managed a good copy Sig 12-24 on FF - my Nikon mount one even better than my Nikon 17-35.

Looking at your website you are much more pro than me. For landscapes and Cathedrals it is by far my most used lens, and like Louis I have read it is pretty much on a par with Nikon 14-24. I do not find it at all unwieldy on OMD, and even if I do get 9-18 for versatilty as well I doubt I will part with it - it is just a gem.

Either way I don't think you can lose. I have no regrets on the total move to Micro 4/3 and now have my gear with me more both on foot and motorbike. Good luck.John
